Trusted Impact Windows & Doors for Lantana Homeowners
Impact windows and doors in Lantana typically cost $650-$2,400 per opening depending on size, glazing specification, and whether the installation meets High-Velocity Hurricane Zone (HVHZ) code. Most full-home installations in Lantana neighborhoods like Hypoluxo Island and the Old Town corridor are completed in 2-4 weeks from measured survey to final inspection, with the written price fixed before any work begins. Call (561) 461-2062 to schedule your measured survey.
Since 2012, Sightline Windows & Doors has installed more than 18,000 openings under the Haven Standard, every one with a written price before a tool was lifted and a documented photo record when the job was done. Lantana sits in Palm Beach County’s HVHZ, where the Florida Building Code requires impact-rated products with Miami-Dade or Florida Product Approval for all new installations and replacements. The salt air off Lake Worth Lagoon accelerates frame corrosion on non-impact units, and the 120+ mph wind exposure in this zone means standard windows fail the inspection that impact-rated products pass. We specify by performance tier and price range, not by margin, drawing from eight manufacturer lines including PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux.
Our technicians are background-checked, uniformed, and identified by license number before arrival, per Haven Clause 3 (Verified Crews). Live phone coverage is available 24/7, not a voicemail queue. The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy.
What Our Impact Windows & Doors Service Includes
Impact-Resistant Windows
Impact-resistant windows use laminated glass bonded to a thermoplastic interlayer, typically polyvinyl butyral (PVB), that holds the pane intact when struck by wind-borne debris. In Lantana, where the Lake Worth Lagoon creates sustained onshore exposure during tropical systems, this specification is not optional for code compliance. We measure every opening for design pressure (DP) rating, specify the appropriate interlayer thickness based on your home’s exposure, and install to HVHZ fastening schedules with documented photo evidence of every anchor pattern.

Hurricane Impact Windows
Hurricane impact windows are tested to ASTM E1886 and E1996 standards for large-missile impact (9-pound 2×4 at 50 feet per second) and cyclic pressure loading. Lantana homes east of Federal Highway and on Hypoluxo Island face the highest design pressure requirements in Palm Beach County. We specify products with Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval, pull permits through Palm Beach County Building Division, and schedule inspections so the installation passes on first review. Your written quote includes the permit cost and inspection coordination.

Single Hung Impact Windows
Single hung impact windows have a fixed upper sash and a lower sash that slides vertically, making them the most cost-effective impact-rated option for Lantana’s typical 1970s-1990s ranch and split-level homes. The reduced moving parts lower air infiltration rates, which matters in Lantana’s climate where summer cooling loads run high. We specify single hung units from CWS and ES Windows with U-factors below 0.30 and SHGC below 0.25 for energy code compliance, and we document the sightline measurement so the frame depth matches your existing wall section without interior trim disruption.

Double Hung Impact Windows
Double hung impact windows allow both sashes to operate, enabling tilt-in cleaning from inside the home. This matters in Lantana’s two-story homes near the Intracoastal Waterway where exterior ladder access is restricted by seawalls and landscaping, a challenge we also address with Impact Windows & Doors in Wellington. We specify double hung products with reinforced meeting rails and dual cam locks that resist forced entry, particularly important for ground-floor installations in the Old Town area. The measured survey records your existing sill angle and jamb depth so the replacement unit seals against water intrusion during driving rain.

Horizontal Roller & Sliding Impact Windows
Horizontal roller impact windows operate on a tandem roller system that allows wide openings without the structural load of a fixed picture window. They’re specified for Lantana homes with pool-facing elevations where the opening width exceeds 72 inches and the homeowner wants operable ventilation, as with our Impact Windows & Doors in Royal Palm Beach. We measure the sill level for drainage slope, specify weep hole configurations that resist wind-driven rain, and install with stainless steel rollers rated for 10,000+ cycles in salt-air environments. The written scope includes the roller material specification and warranty term.

Vinyl Impact Windows
Vinyl impact windows use multi-chambered PVC frames with internal aluminum reinforcement, offering the lowest maintenance option for Lantana’s salt-air climate where aluminum frames require annual inspection for pitting. The thermal break properties of vinyl reduce condensation on interior surfaces during humid winter mornings common to this area. We specify vinyl impact products from ECO Window Systems and CWS with co-extruded color-through capstock, not painted surfaces, and we document the frame expansion coefficient so the installation accounts for seasonal movement without seal failure.

Wind Mitigation & HVHZ Code Compliance
Wind mitigation is the documented verification that your windows and doors meet or exceed the Florida Building Code’s prescriptive requirements for your specific wind-borne debris region. In Lantana, this means HVHZ compliance for all products, proper installation according to the manufacturer’s NOA, and permit finalization that generates a wind mitigation form (OIR-B1-1802) for your insurance carrier. We pull permits, coordinate inspections, and provide the completed wind mitigation documentation as part of every installation. This can reduce your homeowner’s insurance premium by 10-45% depending on your carrier and other mitigation features.

Brands We Service for Impact Windows & Doors

We specify from eight manufacturer lines, selected by what the opening requires, not by what is in stock. For impact-rated aluminum framing in Lantana’s coastal environment, we regularly install CGI’s Estate Collection and CWS’s Aria series, both with Miami-Dade NOA for HVHZ applications. CGI’s proprietary finish system resists salt-air corrosion in the 1,500-foot zone east of Federal Highway where standard anodized aluminum shows pitting within five years. We’ve installed hundreds of CGI units in Lantana and Lake Worth Impact Windows & Doors projects, and we maintain direct distributor relationships for warranty claim support.
For vinyl impact specifications, we draw from ES Windows and ECO Window Systems, both with Florida Product Approval for Palm Beach County’s wind speed maps. ES Windows’ lineal designs accommodate deeper wall sections common in 1980s Lantana construction without exterior trim build-out. ECO Window Systems offers custom color matching for historic district applications, similar to our Impact Windows & Doors - Greenacres service. Whether you have CGI, CWS, ES Windows, ECO Window Systems, or any other make, we can service, repair, or replace it with documented specifications and a written price before any work starts.

AfterSigns You Need Impact Windows & Doors Right Now
- Visible cracks or delamination in existing glass. Cracks in laminated glass compromise the interlayer’s ability to hold shards during impact, and delamination (milky edges where glass separates from PVB) indicates moisture intrusion that weakens the bond. In Lantana’s humid climate, delamination accelerates once it starts. We document the damage with dated photos and specify replacement units with upgraded edge deletion to resist moisture migration.
- Frame corrosion or seal failure around existing units. White oxidation on aluminum frames, soft spots in vinyl, or visible gaps between frame and wall indicate that the installation no longer resists water or wind. Salt air in Lantana’s coastal zone accelerates this degradation. Our measured survey includes a moisture probe reading of the surrounding wall sheathing to determine if rot remediation is required before new installation.
- Insurance renewal requiring updated wind mitigation. Florida insurers increasingly require current wind mitigation inspections for policy renewal, and older non-impact windows generate unfavorable ratings. If your Lantana home was built before 2002 or has standard windows, replacement with HVHZ-compliant impact products is typically the only path to favorable mitigation credits. We provide the completed OIR-B1-1802 form after permit finalization.
- Difficulty operating sashes or locks. Binding rollers, stuck meeting rails, or inoperable locks indicate frame racking, sill settlement, or hardware corrosion that compromises both security and impact resistance. In Lantana’s sandy soils, foundation movement is common, and window frames distort with the structure. Our survey includes a level check of every sill and documented shimming plan for the replacement installation.
- Planned exterior renovation or stucco repair. If you’re already repairing stucco, repainting, or residing your Lantana home, coordinating window replacement reduces total project cost by eliminating duplicate scaffolding, protection, and finish work. The incremental cost of impact-rated replacement during renovation is typically 15-25% lower than standalone installation because the wall opening is already accessible.
Our Impact Windows & Doors Process - Step by Step

- 1
Measured survey and documented assessment. Our technician arrives at your Lantana home with a background check clearance, uniform, and license number for verification per Haven Clause 3. We measure every opening for width, height, depth, sill angle, and wall section composition. You receive a copy of the measured survey to keep. We photograph existing conditions, note any water damage or structural concerns, and record the findings in writing.
- 2
Written price and product specification. Haven Clause 1 requires that the measurement and the quote are the same document. Within 24-48 hours of survey completion, you receive a written scope with line-item pricing for each opening, including the manufacturer, series, DP rating, U-factor, SHGC, and installation method. The price cannot differ from the measured survey. We also provide a free second opinion on any competitor’s written estimate.
- 3
Permit application and product ordering. Upon approval, we submit permit applications to Palm Beach County Building Division with the manufacturer’s NOA or Florida Product Approval documentation. Product lead times vary by manufacturer and specification, typically 4-8 weeks for standard sizes and 8-12 weeks for custom geometries. We communicate confirmed delivery dates and schedule installation accordingly.
- 4
Installation with documented evidence. Our crew arrives on the scheduled date with the specified products, verified fastening hardware, and inspection documentation. We install to the manufacturer’s NOA fastening pattern, photograph every anchor, seal joint, and flashing detail, and conduct a water infiltration test where accessible. The photo record is uploaded to your job file before we leave the site.
- 5
Inspection, finalization, and warranty documentation. We coordinate Palm Beach County inspection scheduling, address any inspector comments, and obtain the certificate of completion. Your final packet includes the permit, inspection approvals, wind mitigation form (OIR-B1-1802), photo record, and the 365-Day Done Right Promise documentation. Haven Clause 4 (Evidence on Every Job) and Haven Clause 5 (No Surprises) are satisfied in writing.
How Much Does Impact Windows & Doors Cost in Lantana?
A typical single hung impact window installation in Lantana runs $650-$1,150 per opening for standard sizes up to 101 square feet, including removal, disposal, HVHZ-compliant installation, permit, and inspection. Double hung impact windows range $850-$1,450 due to the additional operating hardware and reinforcement. Horizontal roller impact windows for large openings run $1,200-$2,400 depending on width, screen configuration, and DP rating required for your exposure. Full-home replacements in Lantana’s typical 2,000-square-foot residences range $12,000-$28,000 for 12-22 openings, with the lower end representing vinyl single hung specifications and the higher end representing aluminum double hung or custom geometries.
Several factors move price within these ranges. Wall section depth determines whether standard jamb extensions suffice or custom build-outs are required, common in Lantana’s 1960s-1970s concrete block construction with shallow window pockets. Stucco repair and interior trim replacement add $150-$400 per opening depending on finish matching. Custom colors or woodgrain laminates add 10-18% to base product cost. Second-story installations with limited exterior access may require scaffolding, typically $400-$800 for the project.
To avoid overpaying, compare written quotes line by line, not bottom line. Some Lantana contractors quote standard windows with “impact options” that don’t carry Miami-Dade NOA, or they omit permit costs that appear later as change orders. Our written price includes every line item before work starts. The free estimate is exactly that: free, with no obligation and no pressure to decide on site.
